The Results of the United States Trial of the Technomed Sonolith 2000 Lithotripter: A Preliminary Report
The Technomed Sonolith 2000 lithotripter utilizes shock waves generated by an underwater spark discharge as its energy source and a lateral ultrasound arm for kidney stone localization. Patient coupling is by immersion of the flank into a limited water bath. An enlarged ellipsoid with a 22 cm aperture combined with the Diatron generator allows most treatments with intravenous sedation only.
To date, 142 patients have been treated in the United States with 84 (59%) becoming stone free, 35 (25%) being left with residual fragments < 3 mm, and 23 (16%) having fragments > 4 mm in diameter. Multiple treatment sessions were required in 15 of 144 patients (10.4%). Complications were minimal.
The Technomed Sonolith 2000 lithotripter provides efficient, low-cost lithotripsy with minimal patient radiation exposure utilizing a portable device.
